Product description:
Sack gabions are cylindrical baskets made of 8x10 double twisted steel woven wire mesh. All Sack Gabions are supplied in the collapsed form, folded and bundled. The bundles are compressed and strapped together at the factory for easy shipping and handling. Lacing wire is supplied in coils. Ring fasteners are shipped in boxes which must be stored in a dry environment.
Filled with stones, sack gabions are used in river control and various emergency works. During the manufacturing process, it is supplied with steel reinforcing wires inserted to facilitate closing during installation.
Treatment: Electro galvanized.
Assembly of Sack Gabions
Sack Gabions are manufactured with all components mechanically connected at the production facility. ?
The folded Sack Gabion units shall be taken out from the bundle and placed on a hard flat surface. They shall be opened, unfolded and pressed out to their original shape ready for assembly.
Foundation preparation
The foundation on which the Sack Gabions are to be placed need not be leveled and graded as Sack Gabions are used for the purposes of providing a firm platform in areas where poor founding conditions exist or in areas where founding occurs in the wet.
Appropriate measures shall be taken for separation of the foundation layer from the rock filled Sack Gabion in accordance with the project specifications (geotextile, drain works, etc.). Geotextiles required to be installed behind or underneath.
Sack Gabion structures shall comply with the requirements of the project specification.
Lacing
Sack GabionsSack Gabions are assembled by rolling the mesh panel into a cylindrical shape and overlapping the selvedged edges. By pulling and tightening the lateral spiral wire, the edges are secured. Excess spiral wire shall be secured around the selvedge wire by looping and twisting the wire around itself. Once the longitudinal overlap is secured, the one end of the cylinder can be laced closed. This is accomplished by pulling the two ends of the bottom spiral tightly together and securing by again looping and twisting the wire around itself. Care shall be taken to avoid damaging the wire coating. The remaining end of the cylinder is left open to allow the Sack Gabion to be filled with suitable stone.
Placement
To facilitate placement, Sack Gabions can be placed individually or in pairs, provided they are laced together. When lifting Sack Gabions, care should be taken to lift the Sack Gabion by the thicker wire.
